BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to the measuring and recording of asubsurface wellbore's thermal conditions during wireline or slicklinelogging operations-. More particularly, the present invention relates toa cable mounted (or slickline mounted) device for measuring andrecording the maximum borehole temperature of a subsurface wellborethrough the deployment of one or more temperature sensitive strips thatmay be disposed in the cable mounted (or slickline mounted) device.

Background of the Invention

Wireline logging is a common operation in the oil industry wherebydown-hole tools are conveyed on wireline (also known as “e-line” inindustry parlance) to acquire data or perform services in either theopen-hole or cased-hole sections of a wellbore. Some cased-hole servicescan also be conducted by slickline. During these wireline or slicklinelogging operations, maximum borehole temperature may be an importantmeasurement to record and obtain. For instance, after severing a stuckdrill pipe with an explosive cutter, cement may need to be pumped somedistance above the severed pipe before side tracking the wellbore. Assuch, a maximum recorded temperature at the severing depth may beessential for designing a cement mix and ensuring a retardant may beproperly matched to the environment. Without having temperature data,there may be risk in having a problematic cementing job.

Currently, an operator may acquire maximum borehole temperature by usingan electronic recording system and/or thermo-couple built into atool-string or mounted on a cable. By this method, data may either betransmitted to surface or recorded in memory during a logging run foranalysis, which may reveal the maximum borehole temperature observedduring the run. However, not all tool-strings are faceted with therequired sensors that record temperature, and those that are may recordinternal tool temperature (affected by electronic heating) as opposed tothe external mud column temperature. Further, on certain tool-strings,such as slim free-point tools used in pipe-recovery operations, theremay be no electronic means of recording maximum temperature. Therefore,using an electronic recording system and/or thermo-couple may not be aviable or accurate option for obtaining maximum borehole temperature.

Alternatively, an operator may deploy mercury thermometers on atool-string for a logging run and manually document their recordedtemperatures. However, the regulations that may restrict their useglobally, their questionable accuracy and resolution, and theirfragility during operations, makes utilizing mercury thermometersimpractical and inaccurate, particularly in the event of wireline jarsbeing fired to free a stuck tool-string. Further, slim free-point toolsmay not have the capacity or space for mercury thermometers to beattached to the tool-string.

Consequently, there is a need for a cable mounted wireline thermalstandoff, compatible with both common and slim-hole services, comprisingone or more temperature sensitive strips that may accurately andreliably measure and record the maximum borehole temperature during awireline or slickline logging run.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIGS. 1A and 1B illustrate an embodiment of a wireline thermal standoff(WTSO) 2. In embodiments, WTSO 2 may be a device for installation on awireline or slickline cable a certain distance above a wellbore loggingtool. In embodiments, WTSO 2 comprises two cable insert halves 4, twoopposing WTSO body halves (an upper body 6 and a lower body 8), and aplurality thermal half shells 10. As illustrated, cable insert halves 4and upper and lower bodies 6 and 8 may be fastened together onto a cable14. Further, thermal half shells 10 may be internally disposed betweencable insert halves 4 and upper and lower bodies 6 and 8. Inembodiments, cable 14 may be any suitable cable for use with anywellbore logging tool. As previously mentioned, cable 14 may be, withoutlimitation, a wireline or slickline. Further, coupling of thesecomponents onto cable 14 may be accomplished using screws, bolts,anti-shear dowel pins, spigots, or any combinations thereof.

FIGS. 2A and 2B each illustrate an exploded view of WTSO 2 from opposingperspectives. As illustrated, cable insert halves 4 may beconcentrically disposed between cable 14 and upper and lower bodies 6and 8, while thermal half shells 10 may be concentrically disposedbetween cable insert halves 4 and upper and lower bodies 6 and 8. Bythis configuration, cable insert halves 4 may be in direct contact withcable 14 and at least partially encased within upper and lower bodies 6and 8 and thermal half shells 10. In embodiments, cable insert halves 4may mate together to form a central bore in which to pass cable 14through WTSO 2. Each cable insert half 4 may be in the general shape ofa hollow, half cylinder and comprise flanged ends 16 disposed about theend portions of each cable insert half 4 and a central flange 18disposed about the middle portion of each cable insert half 4. Flangedends 16 and central flanges 18, alone or in combination, may be used toprevent axial movement of cable insert halves 4 within WTSO 2. Inembodiments, flanged ends 16 may be tapered and between about 0.75 cmand about 1.5 cm in length to match the external tapered portions of theWTSO 2. Further, flanged ends 16 may extend beyond upper and lowerbodies 6 and 8, while the remaining portions of each cable insert half4, including central flanges 18, may fit into corresponding cable insertrecesses 24 disposed on upper and lower bodies 6 and 8 when outfittedwith thermal half shells 10. In embodiments, each central flange 18 maycomprise one or more cable insert fastener threads 20 which receive oneor more cable insert fasteners 26 and one or more anti-rotation spigotrecesses 22 which receive one or more anti-rotation spigots 30. Asillustrated, each cable insert half 4 may comprise two cable insertfastener threads 20 to correspond with two cable insert fasteners 26 andone anti-rotation spigot recess 22 to correspond with one anti-rotationspigot 30.

In embodiments, cable insert halves 4 may be available in various sizesto ensure the central bore diameter of WTSO 2 corresponds to thediameter of cable 14. In embodiments, cable 14 may vary in diameterbetween about 5.0 mm and about 20.0 mm. During installation of WTSO 2,cable insert halves 4 may be configured to slightly deform around anouter armor of cable 14 to prevent physical damage to the cable. Toaccomplish this deformity, cable insert halves 4 may be manufacturedfrom any suitable material, such as, without limitation, aluminum andother soft metals. Further, cable insert halves 4 may be disposable. Inembodiments, cable insert halves 4 may be manufactured from aluminum,and because aluminum may be considerably softer than the armor of cable14, there may be a reduced risk of damage to the wireline or slicklineduring installation of WTSO 2. At installation, cable 14 may be anysuitable diameter required for a particular logging operation and mayeven vary in diameter size along its length, taking into account anymanufacturing tolerances and varying degrees of wear or distortion.Therefore, a range of different cable insert halves 4 may be employedfor a plurality of WTSOs 2 installed on cable 14 to ensure a proper fitalong the length of cable 14 and prevent slippage on and/or damage tocable 14. In embodiments, the length of cable insert halves 4 may bebetween about 10.0 cm and about 20.0 cm, or alternatively between about10.0 cm and about 15.0 cm.

As set forth above, cable insert halves 4 may be at least partiallyencased within the opposing WTSO body halves of upper and lower bodies 6and 8 and thermal half shells 10. Upper and lower bodies 6 and 8 may beof similar structure and in the general shape of a tapered half cylindercomprising an inner surface 32 and an outer surface 34. In embodiments,inner surface 32 of both upper and lower bodies 6 and 8 may compriseportions of cable insert recesses 24 and thermal half shell recesses 25,that together, may be configured to receive thermal half shells 10 andcable insert halves 4. The portions of cable insert recesses 24 maycomprise anti-rotation spigots 30 and insert fastener clearance holes 28that may extend from inner surface 32 to outer surface 34 of upper andlower bodies 6 and 8. Thermal half shell recesses 25 may each compriseat least two thermal windows 31 that may be cut outs in upper and lowerbodies 6 and 8, and further a thermal undercut 33 that may be a groovedisposed on inner surface 32 that connects thermal windows 31 and actsas a channel between the windows.

In embodiments, thermal half shell recesses 25 may be configured inshape to accurately receive thermal half shells 10. Each thermal halfshell 10 may be in the general shape of a hollow, half cylindercomprising an inner circumference and an outer circumference. Further,each thermal half shell 10 may be manufactured from any suitablematerial including, without limitation, stainless steel or otherhigh-performance material. While received by each thermal half shellrecess 25 at the outer circumference, the inner circumference of eachthermal half shell 10 may be configured to receive a portion of eachcable insert half 4. Therefore, upon assembly of WTSO 2, the innercircumferences of thermal half shells 10 may be in contact with cableinsert halves 4 and the outer circumferences of thermal half shells 10may be in contact with thermal half shell recesses 25. In order toprevent radial movement or rocking within WTSO 2 upon assembly, thermalhalf shells 10 may comprise spiral pins 37. Each thermal half shell 10may comprise any suitable number of spiral pins 37, measuring at anysuitable diameter, and disposed at any suitable location on thestructure. In embodiments, each thermal half shell 10 may comprise twospiral pins 37, measuring between about 1 mm and about 5 mm, anddisposed on the top-side or bottom-side of the structure. Further, anynumber of pairs of thermal half shells 10, and by extension, any numberof thermal half shell recesses 25 may be present within WTSO 2. Asillustrated in FIGS. 2A and 2B, WTSO 2 may comprise two pairs of thermalhalf shells 10 disposed about cable insert halves 4 and disposed withinfour thermal half shell recesses 25 of upper and lower bodies 6 and 8.

In embodiments, each thermal half shell 10 may be provided externalexposure by thermal windows 31 and thermal undercut 33. In particular,thermal windows 31 and thermal undercut 33 may provide external exposureto thermal strips 35 disposed about the outer circumference of eachthermal half shell 10. In embodiments, thermal strips 35 may betemperature test strips capable of measuring and recording material,surface, or surrounding temperatures, without limitation, from about 20°C. to about 400° C. Further, thermal strips 35 may be fixed to thermalhalf shells 10 by any suitable means. In some embodiments, thermalstrips 35 may be fixed to thermal half shells 10 with an adhesive.

In embodiments, cable insert recesses 24 (formed by upper and lowerbodies 6 and 8 together with thermal half shells 10) may be configuredin shape to accurately receive cable insert halves 4, such thatanti-rotation spigots 30 fit into anti-rotation spigot recesses 22, thuspreventing radial rotation of cable insert halves 4 within WTSO 2.Further, cable insert halves 4 may be secured within cable insert recessportions 24 with cable insert fasteners 26, such that cable insertfasteners 26 may travel through insert fastener clearance holes 28 to bereceived by or fit into cable insert fastener threads 20, and sit flushwith outer surface 34 of upper and lower bodies 6 and 8. In embodiments,cable insert fasteners 26 may be any suitable fasteners, bolts, orscrews such as, without limitation, small cap head bolts or screws. Inembodiments, cable insert fasteners 26 may have a diameter of 3 mm(i.e., M3 bolts).

In embodiments, upper and lower bodies 6 and 8, which securely encasecable insert halves 4 and thermal half shells 10, may be coupledtogether onto cable 14. Coupling of upper and lower bodies 6 and 8 ontocable 14 may be accomplished via dowel pins 36 and dowel pin recesses38. In embodiments, dowel pin recesses 38, configured to receive dowelpins 36, may be disposed on inner surface 32 of both upper and lowerbodies 6 and 8. In embodiments, one dowel pin 36 may correspond to twodowel pin recesses 38, one recess being disposed on inner surface 32 ofupper body 6 and the other recess being disposed on inner surface 32 oflower body 8. As illustrated in FIGS. 2A and 2B, upper body 6 and lowerbody 8 may each comprise four dowel pins recesses 38 to receive fourdowel pins 36. In embodiments, dowel pins 36 may be 4×8 mm pins, oralternatively 4×6 mm pins. In an alternative embodiment, upper body 6 orlower body 8 may be machined to include pegs acting as dowel pins 36that are received by corresponding recesses 38 disposed on the opposingbody.

In addition to dowel pins 36 and dowel pin recesses 38, coupling ofupper and lower bodies 6 and 8 may be accomplished via clamping bolts40, clamping bolt female threads 42, and clamping bolt clearance holes44. In embodiments, clamping bolt female threads 42 may be disposed onupper body 6 or lower body 8 with corresponding clamping bolt clearanceholes 44 disposed on the opposing body relative to clamping bolt femalethreads 42. For instance, as illustrated on FIGS. 2A and 2B, clampingbolt female threads 42 may be disposed on inner surface 32 of lower body8 and have corresponding clamping bolt clearance holes 44 disposed onupper body 6. In embodiments, clamping bolt clearance holes 44 mayextend from inner surface 32 to outer surface 34. Upper body 6 or lowerbody 8 may comprise four clamping bolt female threads 42 or fourclamping bolt clearance holes 44, or any combinations thereof. Inembodiments, clamping bolts 40 may travel through clamping boltclearance holes 44 and may be received by or fit into clamping boltfemale threads 42, such that upper and lower bodies 6 and 8, along withcable insert halves 4 and thermal half shells 10, may be securelycoupled and clamped onto cable 14. During installation, clamping bolts40 may be torqued to a consistently safe limit with a calibrated torquewrench which in turn may reduce the risk of damage to cable 14 fromcable insert halves 4 when clamping bolts 40 may be tightened. Inembodiments, clamping bolts 40 may be any suitable fasteners, bolts, orscrews such as, without limitation, four large cap head bolts or screws.In embodiments, clamping bolts 40 may have a diameter of 6 mm (i.e., M6bolts).

In further embodiments, upper body 6 and lower body 8 may compriselanyard holes 62 disposed on outer surface 34. Lanyard holes 62 maytravel through one of the tapered portions of upper and lower bodies 6and 8. As illustrated in FIGS. 2A and 2B, upper body 6 may compriselanyard hole 62 and lower body 8 may comprise another lanyard hole 62.Lanyard holes 62 may be used to connect WTSO 2 to a lanyard duringinstallation or removal onto cable 14 for added security and to avoiddropping the device down the wellbore.

The two opposing WTSO body halves, upper body 6 and lower body 8, may bemanufactured from any suitable material such as, without limitation,stainless steel or other high-performance material. Further, upper andlower bodies 6 and 8 may also be surface hardened (e.g., vacuumhardened) to improve wear resistance during use. Further, upper andlower bodies 6 and 8 may be available in various sizes to accommodatethe wellbore in which WTSO 2 may be used. In embodiments, the length ofupper and lower bodies 6 and 8 may be between about 10.0 cm and about15.0 cm, or alternatively between about 12.0 cm and about 13.0 cm.Further, the diameters of upper and lower bodies 6 and 8 may range fromabout 4.0 cm to 10.0 cm according to the application.

When fully assembled, referring once again to FIGS. 1A and 1B, WTSO 2may have an outer diameter of about 4.0 cm or greater. In alternateembodiments, WTSO 2 may have an outer diameter measuring about 7.4 cm.WTSO 2 may minimize contact area of cable 14 within the wellbore duringlogging operations and allow for standoff rotation under the action ofcable torque. WTSO 2 may allow for easy rotation, both axial and radial,should cable 14 rotate when it is deployed and retrieved from thewellbore. The general nature of a wireline or slickline cable duringlogging operations is to rotate. Rotation may be caused by opposing layangles of inner and outer armors and induce unequal torsional forceswhen tensions are applied. As such, the design of WTSO 2 may allow foreasy rotation of cable 14 during logging operations, avoiding, forexample, the potential for damage if excessive torque was allowed tobuild up.

Further, WTSO 2 may be capable of measuring and recording a wellbore'smaximum temperature via thermal windows 31, thermal undercut 33, andthermal strips 35. In embodiments, thermal windows 31 may allow thermalstrips 35 to be exposed to surroundings for temperature measurement,while maintaining pressure equalization via thermal undercut 33. Forinstance, during operation, WTSO 2 may come in contact with mud disposedin the wellbore. The mud may enter through a first thermal window 31,travel through a thermal undercut 33, and exit out a second thermalwindow 31, thus coming in contact with a thermal strip 35. By thisprocess, WTSO 2 may be capable of measuring or recording maximumtemperature of the wellbore. Further, because WTSO 2 may comprise aplurality of thermal strips 35, an operator may be capable of finding anaverage maximum temperature of the wellbore as well as an accuratemaximum temperature.

In further embodiments upon full assembly, WTSO 2 may comprisedisassembly cutouts (not illustrated). Sometimes during the disassemblyor removal of WTSO 2 from cable 14, WTSO 2 may become stuck or fixed tothe wireline or slickline. In such case, a parting tool or special jigmay be used to pry WTSO 2 from cable 14. In embodiments, the partingtool may utilize disassembly cutouts disposed on inner surface 34 ofupper and lower bodies 6 and 8 to achieve leverage when disengaging astuck WTSO 2 from cable 14.

FIG. 3A illustrates a generic logging operation that includes aplurality of WTSOs 2 coupled to cable 14 in accordance with oneembodiment of the present invention. As illustrated, plurality of WTSOs2 may be clamped onto cable 14. Cable 14 may be, for example, stored ona wireline drum 72 and spooled into the well by a winch driver andlogging engineer in a logging unit 74. In the illustrated embodiment,logging unit 74 may be fixed to the drilling rig or platform 76, andcable 14 may be deployed through a derrick 78 via at least two sheavessuch as an upper sheave 68 and a lower sheave 70 to the maximum depth ofthe wellbore. The wellbore may have an open-hole or cased-hole portion66. As illustrated, WTSOs 2 may be installed on cable 14 in open-hole orcased-hole portion 66. A logging tool 80 may be connected to the lowerend of cable 14 to take, for example, measurements involving the stateof tubing, casing, cement, or perforations of the wellbore. The numberof WTSOs 2, and their positions on cable 14 may be determined by anumber of factors, including for example, the length of the open-hole orcased-hole portion 66, the location at which an operator wishes torecord temperature, the location at which logging tool 80 needs toreach, and the overall trajectory of the wellbore, which may be deviatedor directional in nature. In embodiments, WTSOs 2 may be deployed at anysuitable distance above a logging tool such that they remain within acasing or open-hole portion. Further, WTSOs 2 may be used in addition toother cable standoff-type devices. FIG. 3B illustrates a close-up viewof a single WTSO 2 attachment to cable 14 taken along circle 82. In theillustration of FIG. 3B, WTSO 2 may be seen in relation to cable 14, awellbore wall 84, and the wellbore.
